The mixture of the testosterones are time-released to provide an immediate effect while still remaining active in the body for up to a month. As with other testosterones, Sustanon¸is an androgenic steroid with a pronounced anabolic effect. Therefore, athletes commonly use it to put on mass and size while increasing strength. However, unlike other testosterone compounds such as cypionate and enanthate, leads to less water retention and estrogenic side effects. This characteristic is extremely beneficial to bodybuilders who suffer from gynecomastia yet still seek the powerful anabolic effect of an injectable testosterone. The decreased water retention also makes Sustanon a desirable steroid for bodybuilders and athletes interested in cutting up or building a solid foundation of quality mass. A common dosage for Sustanon would range from 250 mg to 1000 mg per week. Although it remains active for up to a month, injections should be taken at least once a week to keep testosterone levels stable. A steroid novice can expect to gain about 20 pounds within a couple of months by using only 250 mg of Sustanon a week. More advanced athletes will obviously need higher dosages to obtain the desired effect. It is a fairly safe steroid, but in high dosages, some athletes may experience side effects due to an elevated estrogen level. With dosages exceeding 1000 mg a week, it is probably wise to use an antiestrogen such as Nolvadex (tamoxifen citrate) or Proviron (mesterolone). It can suppress natural testosterone production, so the use of HCG (human chorionic gonadotropin) or Clomid (clomiphene citrate) may be appropriate at the end of a cycle. Sustanon is a good base steroid to use in a stack. The most popular way to use it is on a weight gaining cycle in a stack with Anadrol 50 (oxymetholone) and Dianabol (methandrostenolone).
